This study attempted to explore the question whether sex-determined grammatical gender loading in the native language will have an effect on the development of gender identity. The empirical question asked was, Will there be a relationship between the amount of linguistic emphasis on sex-determined gender and the average age of attaining gender identity in children, in a specific language environment? Three groups of children, one in Israel, one in the USA, and one in Finland, were tested on the Michigan Gender Identity Test (MIGIT). The findings indicate a direct relationship between gender loading in the native language and gender identity attainment. It appears that the Israeli children have a significant, albeit temporary, advantage over their American and Finnish counterparts in the timing of gender development.
